UPDATE (18:23, May 18, 2017): Luckey has pushed back against the idea he was using a shell company, saying that “the company they are calling a shell corporation is actually an ongoing business with healthy revenue, multiple employees and mostly non-cash assets...”:

Wings of Time appears to be a company involved with transportation and as such we should have called it a “side company” or “company,” separate from his former gig at Facebook. Fiendlord’s Keep owns Wings. We have updated the story to refer to both as, simply that, “companies,” as it was always our intent to focus on the names Luckey gave them, not their status. We apologize for the confusion.
